I just grep'd the log file and found this, so I think you are correct

root at blhblahblah:/usr/local/samba-4.1.6/var# grep pem *
log.samba:  invalid permissions on file
'/usr/local/samba/private/tls/key.pem': has 0644 should be 0600
log.samba:  Invalid permissions on TLS private key file
'/usr/local/samba/private/tls/key.pem':
log.samba:  Removing all tls .pem files will cause an auto-regeneration
with the correct permissions.
